    Like I said the park light on the dash stays on after pushing in the air valve to release the brakes. Called Pete and they said there is a valve under the kick plate underneath the steering wheel. So I got the part and replaced it. Didn't fix a thing is there another sensor or something that could be causing this? Thanks

    Make sure you are replacing the correct sensor. There should be a label tag on the harness within a few inches of the connector. Some models will be located close or behind the MV3 or park brake valve. Also the sensor should only have air supplied with the park brake released. Another way to clue in on the correct one.
